Transport cost is a critical component that structure price of goods at destination points in international trade. This research explored and analyzed transport cost and its impact on export by gravity model. The two stage least squares (2 SLS) model in the estimation was used, in which for the first stage, the transport cost is regressed on a set of exogenous variables including five instrumental variables that affect transport cost, but do not affect exports.

IMPACT OF TRANSPORT COSTS ON VIETNAMESE TEXTILE EXPORTS Trinh Thi Thu Huong , Pham Thanh Ha2 & Nguyen Ngoc Lan3 Abstract Transport cost is a critical component that structure price of goods at destination points in international trade This research explored and analyzed transport cost and its impact on export by gravity model The two stage least squares (2 SLS) model in the estimation was used, in which for the first stage, the transport cost is regressed on a set of exogenous variables including five instrumental variables that affect transport cost, but not affect exports In the second stage, the forecasted of transport cost enters as one of the regressors of the exports A survey was conducted for data collection purposes Results from the paper show that higher distance and poor partner port infrastructure leads to a notable increase in transport costs Besides, higher importer income, depreciating real exchange rate and better logistics condition facilitate trade growth In contrast, greater transport costs, distance and tariff significantly deter trade Based on the research results, the paper provides recommendations and solutions that encompass a series of policies to effectively reduce the transport cost in textile export in Vietnam Keywords: transport cost, textile export, Vietnam, international trade, distance, infrastructure, tariff Date of receipt: 10th Jun 2016; Date of revision: 15th Nov.2016; Date of approval: 30th Nov.2016 Introduction Since Vietnam implemented trade reform policies and opened its doors for foreign investors, export of textile products has been in a rapid progress and promises a fruitful future Over the last decades, average annual growth rate of Vietnam’s textile export reached 13.62% (UN Comtrade), among the fastest growing sector in Asia Vietnam’s textile products have been currently available in 180 countries and territories in the world and five continents from America, Europe to Africa and Asia According to Vietnam Textile & Apparel Association, Vietnam is going to reach the third place in the world textile export However, the opportunities not go without challenges Despite the fact Faculty of Economics and International Business, Foreign Trade University, Vietnam Corresponding author, E-mail: ttthuhuong@ftu.edu.vn Faculty of Economics and International Business, Foreign Trade University, Vietnam BI Norwegian Business School that tariff measures are declining, transport costs and other non-tariff barriers remain an obstacle for Vietnam’s export Plausible explanations for high transport cost in Vietnam are poor infrastructure and inadequate investment in transport modes Transport costs not only affect the direction of textile export but also influence modal choice and the organization of production, particularly as “just-intime”, “made-to-order” or “off-the-rack” methods get extended to the global level In turn, these new production methods are placing increasing demands on the transport system The study of transport cost and its impact on trade is of relevant interest for economists in both developed and developing world While transport cost varies according to region and time, various researches reach to the same conclusion that it deters foreign trade This paper differs from former research in the way that it investigates the relationship between transport cost and international trade of textile (a specific sector) in Vietnam (a developing country) from 2012 to 2014, with focus on the year 2013 The paper studies the impact of transport costs on the volume and price of international trade To what extent has the rise in international trade been driven by changes in transport costs? Is its magnitude comparable to distance and tariff barriers What implication can be withdrawn from our country’s experience? The paper is structured into five sections First, an overview of Vietnamese textile export is presented The literature review of transport cost and measurement of international trade is then discussed In the third part, the methodology section explains the data collection and the framework for the paper The findings from the study is further presented and explained Finally, the recommendations regarding a set of measures for reducing transport cost and expand the international trade of Vietnam are withdrawn Overview of Vietnam’s textile export 2.1 Export trend Figure demonstrates the value of apparel export in Vietnam over an elevenyear period Apparel export which accounts for most value of textile export, with its turnover increased gradually from $4.8 billion in 2005 to as much as $19.1 billion in 2014 With an impressive total turnover of $135 billion in eleven years, textile in general and apparel in particular currently stand as the second largest export sector of Vietnam Its

markets with 53 countries and territories investing in Vietnam (General Statistics Office, 2015) So far, Vietnam is getting the biggest cake of the orders leaking out from China, Vietnam The export figures show that Vietnam is really growing fast especially in an important market like USA Vietnam has now made a prominent space in the global apparel market and they are expanding their capacity to be ready to cope up with the upcoming opportunities from China and even Bangladesh After China, Vietnam is now the second largest exporter of readymade garments to the two most influential markets-USA and Japan 12 10 China USA Japan EU (27 countries) Korea, Rep Figure 3: Export destinations of Vietnam’s textile and apparel (billion USD) Source: UN Comtrade, 2015 The United States is the largest importer of Vietnamese textile, with the export value in 2014 is 9.8 billion Vietnam is currently the second largest suppliers of textile to the United States, after China, with the export value to the United States in 2014 accounts for 50% the total value of the industry EU is the second consumption of Vietnamese textile, with the export proportion in 2014 accounts for more than 17% of the industry Japan is the third largest importer of Vietnamese textile Japan is famous for their requirement on quality, packing and technical specification However, in recent years since 2011, the relationship between Vietnam and Japan is becoming fruitful and Japan is more willing to invest FDI in Vietnam, including for textile industry Korea is the fast track consumer of textile from Vietnam In 2014, total export from Vietnam to Korea reached $ 2.4 billion, increased 27% compared to 2013 Literature Review 3.1 Determinants of transport cost From the theoretical framework above, we have a function of transport costs as follows: Transport costs = f(distance, geography, infrastructure, trade facilitation, technology, fuel cost, mode, delivery time…) - Distance Transport costs rise in distance, as each kilometer travelled requires fuel, manning and capital expense (Portugal, 2008) Distance is the sea distance to the nearest major world market (Radelet & Sachs, 1998) ran the model on the determinants of shipping cost (CIF/FOB band, log from 1965 to 1990) and concluded that each 10% increase in sea distance is associated with a 1.3% increase in shipping cost - Mode For the mode variable, a strong positive relationship between mode and transport cost as air transport is more costly than sea transport SAS Cargo noted that air transport were 70% more costly than sea transport Martinez (2003) found the significant sign of dummy “mode” when comparing the transport costs of cement by road and ship If cement was exported by road from Spain, the cost increased 5.19% compared to its shipment by vessel - Infrastructure The importer infrastructure variable was added in Limao and Venables (2001)’s model, which showed a statistically significant coefficient with the expected negative sign More interestingly, the inclusion of infrastructure measures improved the fit of the regression since the adjusted R2 changed from 0.2 to 0.31, which corresponded to the importance of infrastructure in determining transport costs Martinez (2003) also concluded that an improvement of 1% in the infrastructure of the destination country lowered transport costs by 0.14% - Delivery time Delivery time impacts not only perishable and agricultural products but also manufactured products It is a plausible proxy for the quality of transport service Martinez (2001) obtained a 0.15 percentage value for the estimated coefficient of transit time, meaning a 1% increase in the delivery time added an extra 0.15% in cost - Technology (Increasing Returns to Scale and Containers) The appearance of containerized transport has been an evolution in transport sector during the last decade Containers not only improve the volume of trade but also change the nature of trade Since the development of containerization, Levinson quoted that “If ever there was a business in which economies of scale mattered, container shipping was it” - Continent, Adjutancy and Language In a model of Martinez (2003), the dummy variables, proxy for certain geographical and cultural characteristics, namely, being neighbors, being an island, being landlocked or sharing a language was not significant A possible interpretation is that they not represent direct trade costs Alternatively, they may indicate cultural similarities, preferences or production effects, which in turn, better trade relation 3.2 Gravity model The paper relies on a classical theoretical framework to assess the relative importance of transport costs on trade: the gravity model, which becomes the workhorse of international trade The gravity model was first introduced by Jan Tinbergen (1962), based on the Newtonian theory of gravitation Tinbergen explained the bilateral trade flow between two countries as the way planets were mutually attracted to each other in proportion to their sizes and proximity Countries which were similar in GDPs and proximity to their partners were more likely to trade Before Tinbergen (1962), Ravenstein (1885) and Zipf (1946) used gravity concepts to model migration flows, but Tinbergen was the first person to develop a gravity equation, which has been improved time by time, to analyze trade between countries In Tinbergen’s version, the gravity model was presented as an intuitive ways of understanding trade flows: Xij=G Si Mj wij where Xij is the monetary value of exports from i to j; Si denotes exporterspecific factors (such as exporter’s GDP and population); Mj represents the factors that affect import demand (importer’s characteristics, such as GDP and population); G comprises all factors that not depend on country i and j, such as the level of globalization Finally, wij is the trade cost between two nations, including tariff and transport cost - Transport Costs and Trade It is obvious that transport cost as an adverse impact on international trade However, it is intriguing to capture the size of the proxies and the size of the barriers Hummel (1999, 2001) ran a model with the freight and tariff variables as an explanation for the value of bilateral imports, summed over all goods, for all country pairs with positive values for trade The average elasticity of freight and tariff for 62 2-digit “goods” were 5.6, implying that a 10% tariff and freight increase lowers trade by 56 percent and markups on the order of 22 percent In addition, rather than being exported with high transport cost, heavy weighted goods such as cork, wood, paper, rubber manufactures and inorganic chemicals were produced at the locations where there was a high demand Limao and Venables (2001) estimated elasticity of transport cost and trade volume on distance and infrastructure The paper did not only prove that the point estimates of trade towards transport costs were -6.47 base on distance and less than -2 base on partner infrastructure measures and border but also reflected the economies of scale through which higher volumes lead to lower costs of transport In contrary to Hummel (1999, 2001), Limao and Venables (2001), Baier and Bergstrand (2001) concluded that reduction in trade costs played a minor path in trade growth With the data of 16 OECD countries from UN Comtrade in the period 1958-60 and 1986-88, his result showed that trade growth was explained 66% by income, 26% by trade liberalization and only 8% by lower transport costs The possible reason for his apparent contradiction to previous study is that the crosssection variation in freight rates in his sample is quite large, while transport costs did not fall very much over time Methodology 4.1 Model specification Traditionally, the multiplicative gravity model has been linearized and estimated using OLS assuming that the variance of the error is constant across observations (homoscedasticity), or using panel techniques assuming that the error is constant across countries or country-pairs We use the two stage least squares (2 SLS) model in the estimation In the first stage of 2SLS, the transport cost is regressed on a set of exogenous variables including five instrumental variables that affect transport cost, but not affect exports In the second stage, the forecasted of transport cost enters as one of the regressors of the exports There are two reasons why the SLS is justifiable Firstly, transport cost is considered an endogenous variable in the export regression and instrumental variables are needed to correct for endogeneity using two-stage estimation procedure Secondly, the error term in the export regression contains unobserved country-specific effects so that the error term may be correlated with the variations in some of the regression For example, shocks in the Gross Domestic Product (GDP) may be highly correlated with the shocks that affect export The tests for endogeneity, the test for over-identification, and the test for strength of instruments are conducted to ensure the robustness of the coefficients, of which the results are all in favor of SLS The first equation in the SLS is: lnTCj = β0+ β1 lnDaysj + β2 lnInfrj + β3 Mode + β4 (Infr*Mode) + β5 lnDistj +β6 (Distj*Mode) + εi The endogenous variable Transport Cost (TCj) is measured by distance (Dj), delivery time (Days), airport and seaports‟ infrastructure (Infrj) and means of transportation (Mode) The second-stage equation of the 2SLS is: lnXj= γ0 +γ1 lnYj+ γ2 lnDistj + γ3 InFTC + γ4POPj +γ5 RER+ γ6 Infr +γ7Tariff+ γ8 ASEAN + γ9 TPP+ γ10 Comcont+ µj where Ln denotes natural logarithms, Xj is the export values of textile and apparels from Vietnam to country j Yj is income in the destination market, FTC is forecasted transport costs, Infr is the infrastructure level of importing country, POPj is the number of population in importing country, RER is the real exchange rate, Tariff is the import tariff of textile in the importing country, ASEAN is a dummy variable which equal to if the importing country is a member of ASEAN and otherwise, TPP is a dummy for TPP countries, Comcont takes value of when countries share the same continent ASEAN in this paper refers to nine official nations, including Brunei, Cambodia, Indonesia, Laos, Malaysia, Myanmar, the Philippines, Singapore, and Thailand Meanwhile, ten TPP countries (trading partner of Vietnam) are Australia, Brunei, Canada, Chile, Japan, Malaysia, Mexico, New Zealand, Peru, Singapore and the United States All the variables except dummies are in natural logs µj denotes the error term that is assumed to be independently normally distributed On the purpose of the study, the null hypothesizes are: H0: Transport Cost has no impact on Export H1: Transport Cost has a negative impact on Export 4.2 Data Of the first stage Our analysis is based on cross-section annual data in 2013 covering export flow of Vietnam and 274 destinations Primary data on transport costs obtained from quotation of shipping lines and their agents A total of 89 surveys were sent 10 and 76 were received, 49 of which from shipping agents and the rest 27 from airline agents The data comprises transport price from Cat Lai, Vietnam to 274 destination terminals and ports The variables studied are identified as follows: - Transport Cost Through an extended interview with logistics staff in various companies, we collect the ocean and air transport cost (freight + surcharges) for the textile shipments The data is mainly constructed based on the quotations of famous shipping lines such as Waiha, Hanjin, K‟Line and SITC Surcharges at departure+ FCL/LCL Freight+ Surcharges at destination = Constant Similar to sea transport cost, we collect air freight and surcharge from various sources through both formal and informal interview and email with airlines, freight forwarders and their agents - Distance The sea distance in kilometer is taken from Searates website, assessed on 25 December, 2015 The chosen port of departure is Cat Lai, District 2, Ho Chi Minh City as the port is responsible for over 80% of Vietnamese exports Also the interview with logistic staff confirms the importance of Cat Lai Port to Vietnam textile exports The database includes information on the distance from Cat Lai, Ho Chi Minh City to main ports in other countries - Infrastructure The sea port infrastructure is taken from Worldbank Database for the year 2013 and 2014 The quality of port infrastructure is scored from to (1= extremely underdeveloped to 7= well developed and efficient by international standards) Meanwhile, the airport infrastructure is the number of paved airports per 1000 square kilometer of each country The data of number of paved airport is obtained from CIA Factbook 2013 and 2014 while the land area is drawn from the World Bank’s Indicator Of the second stage - Export Xj is denoted as export of all textile products from Vietnam to country j in 2013 in million US dollars The study includes the export data of Vietnam to 75 countries from UN Comtrade The original database does not contain any 11 - Income and Population Data on GDP and population are sourced from the World Development Indicators (WDI), World Bank - Logistics Logistics data is the quality of trade and transport-related infrastructure (1=low to 5=high), which is also taken from Worldbank Database Logistics performance index is constructed on a rating scale from (very low) to (very high) - Tariff Import tariff of partner’s countries is taken from WITS (COMTRADE) database It is generally assessed on the CIF value of the goods Effectively applied tariff is the type of tariff levied on components, rather than finished products when the origin of a product is from more than one country - Real Exchange rate (RER) RER is bilateral real exchange rate between Vietnam and country j in 2013, which is calculated as the product of the nominal exchange rate and relative price levels in each country 12 Results 5.1 Finding and discussion Table: Descriptive statistics

illustration 13 Determinants of transport cost We have tried several specifications, by testing for the significance of the explanatory variables Since the interaction terms Infr*Mode and Dist*Mode may correlate with Dist, Infr and Mode variables, we run a multicollinearity test to see if there is any problem A higher VIF (variance inflation factor) after the introduction of interaction terms is observed, however, R and the standard error of the equation not change much Therefore, we can safely ignore the multicollinearity problem with interaction terms The first analysis shows results which exclude the interaction terms (Infr*Mode and Distance*Mode) A number of conclusions were reached First, the days coefficient has the expected positive sign, showing that a 1% increase in time to export increases transport costs in approximately 0.35% (Model 1) The distance (from Cat Lai to destination ports) variable also has the expected positive coefficient, indicating that a higher distance is associated with higher transport costs It is clear that distance has a strong impact on export (0.356), which is higher to those found in other studies of Hummels (1999) where distance coefficients range from 0.2-0.3 and Kumar and Hoffmann (2002) with a distance elasticity of 0.24 Transport Costs and Export An improvement of 1% in the infrastructure of the destination country lowers transport costs by approximately 1.2%, which is seven times higher than the magnitude of the port infrastructure coefficient in Marzinez et.al (2004) where the port infrastructure was captured for ship mode only The infrastructure variable is likely to interact with the mode dummy when we consider the infrastructure of seaports and airports As air shipping is much more costly than sea shipping, an improvement in airport infrastructure would not be sufficient to compensate for the higher prices that the traders have to pay The model is estimated for a sample of 207-216 observations with 2013 data All the analyses explain 68 to 81 percent of the variations in direction of trade flows We use the forecasted transport costs as an explanatory variable of textile export since the result from the Hausman (1978) test indicates that transport costs must be considered as endogenous in the import demand equation (IV estimation) Then, we compare the results with those obtained when using distance 14 as a proxy for transport cost The analysis presents the OLS results for the baseline case, which excludes the distance, tariff and dummies The coefficient on distance is negative signed and more significant than that of the forecasted transport costs The standard variables are population, income, real exchange rate and logistics As a fashionable product, apparel is quite sensitive to income (Yj) Wealthy and prosperous nations tend to pay more attention to their outlooks and seek for diversification in design, sophisticated tailor-made and materials from developing countries They are willing to place an order to Vietnam factories as reasonable price coming from cheap labor source would offset transport and related costs Demographic variable (Pop) is statistically significant and positive in mode (1) The more populous the countries are, the greater demands they have for apparels and clothes In high income and sparsely populated nation, increase in population may indicate a rise in birthrate and a growing demand for child wear However, it is argued that higher population reduces income per capita and makes each individual poorer, reducing demand for imports Logistics variable is seen to be the strongest determinant of export More specifically, a one-percentage rise in the importer’s logistics index would raise Vietnam’s export by nearly 3.8%, ceteris paribus This variable, however, gradually lose its magnitude and significance when we introduce other variables In the second analysis, we add the distance (Dist) variable and compare it with the forecasted transport cost (FTC) variable The magnitude of distance indicates that a rise of 1% remoteness between two nations leads to a decrease in export of 0.99%, which triples the 0.32% magnitude of forecasted transport cost Furthermore, tariff variable (Tariff) is added to include the non-tariff barriers towards trade flow It is apparent that the magnitude of forecasted transport costs (0.303) is bigger than that of tariff (-0.176) However, it is quite interesting to see that once these dummy variables namely ASEAN, TPP and Comcont are included in the analysis, the impact of tariff turns out to be greater than that of transport cost The implication is that the trade agreement lowers tariff and directly influences export through tariff channel The coefficient of the ASEAN variable (γ8) takes a negative sign and is 15 statistically significant at the percent level Our results are quite similar to Nguyen (2010) It is apparent that ASEAN accounts for a smaller market share vis-à-vis non-ASEAN members in terms of gross domestic product and market size The effect from ASEAN is quite marked, resulting in trade diversion of 0.7% The result indicate that Vietnam is more integrated into textile trades with non-ASEAN countries than that with ASEAN members The impact of TPP has not been not significant enough to be shown in statistics A plausible explanation is that TPP has not been successful due to conflicting interests among its members The proposal and implementation of TPP regulations still challenge Vietnamese textile exporters, especially the “yarnforward rule” Moreover, apart from the US and Japan, potential customers of Vietnamese textiles are other TPP members such as, Chile, Peru and New Zealand Finally, the forecasted transport cost (FTC) is replaced by distance (Dist) The fitness of the equation is better with all the variables explain about 81% of the trade flow A likely reason for this finding is that distance influences export value through channels other than freights and surcharges For example, the costs to find information, translate languages and investigate culture are bound to add up trade costs Conclusion and implications 6.1 Conclusion It is a common belief that transport cost is decreasing and that international trade is not affected by freight rate as much, especially for light-weighted textile products Our results from Vietnam’s practice reveals that freight does not decrease from 2012 to 2014 and it possibly increases slightly, depending on the destinations In addition to analyzing freight rate, we take into account surcharges which increase or decrease unpredictably and unregulated by any law and regulation Another contribution of the research to the existing literature of Vietnam is that it takes into consideration the cost of transportation by air We acknowledge that sea transportation is the most common mode in the survey sample (accounting for 70%); however, there is a growing interest in air transport as well for the goods that are of high value, time and reliability Our results from the first estimations show that higher distance and poor 16 partner port infrastructure leads to a notable increase in transport costs Inclusion of time, mode and common continent variables improve the fit of the regression Transporting a cargo by air is much more expensive than by ship Also, lead time is considered money, so Vietnamese government should assist exporting enterprises by improving public infrastructure and simplify the existing customs clearance Our results from the second estimation show that higher importer income, depreciating real exchange rate and better logistics condition facilitate trade growth In contrast, greater transport costs, distance and tariff significantly deter trade In every case, distance is the best proxy for trade cost in the textile sector Transport cost has larger impact than tariff only when free trade agreements are not included However, there are still some limitations in our study First of all, since the freight rate in Vietnam is quite confidential within shipping lines, their agents and customers, we act as a typical cargo owner (customer of shipping lines) The freights and surcharges that the shipping lines informed us could be higher than the real market price, when shippers and ship owners have business relationship and trust each other The paper also takes information from a sample of ship owners so there would exist the problem of selection bias and allocation concealment More crucially, the research ignores the inland transport costs, which might be a great issue in developing country such as Vietnam We expect that further study on trade and transportation would cover the issue and bring more policy implications for the policy makers and the Vietnamese government 6.2 Implications - Improving sea port and airport infrastructure The first implication to reduce ocean transport cost in Vietnam is to improve port infrastructure According to Eric Johnson (2010), port and other infrastructure projects in Vietnam have been delayed significantly In accordance with other studies such as Tae (2010), a proposed solution is that Vietnam should cooperate with domestic ports and foreign counterparts to improve port efficiency This approach attracts foreign direct investment in port infrastructure, saves cost for the state budget and shares the risk with other entities In addition, port services, especially at Cat Lai and Dinh Vu should be priotized to optimize ship schedule plan, labor plan and inventory and warehouse plan The infrastructure development is forecasted to bring about huger container volume across Vietnam’s ports 17 Beside sea freight, a critical component of the air transport sector which needs improvement is airport infrastructure Vietnam will need more investment in new terminals, longer runways and upgraded equipment to keep up with increases in air passenger traffic, which is estimated by the Civil Aviation Administration of Vietnam (CAAV) to increase 10 per cent-12 per cent a year during 2015-2020 The master plan envisages 26 airports in operation by 2020, including 10 international airports and 16 domestic airports Foreign companies will be allowed to invest in the form of BOT As no such project has yet been done in Vietnam, there are a myriad of technical details to be overcome before such a project comes to fruition - Disclosing freight information Vietnam freight market was considered unfair competition and oligopolistic market Auxiliary and unreasonable charges and freights have been in a sudden increase or decrease from shipping lines The Ministry of Transportation should report Government statement on the matter and strengthen inspection and test regular shipping companies, seaports, finding the remedies to control charges, surcharges in amending the Vietnam Maritime Law to help promulgate and public the freight rate of any charges on maritime shipping companies which have business operations in Vietnam Besides, our legislation should prohibit the practice of unreasonable charges which not in accordant to international practice - Reducing lead time in textile industry As discussion above, it is clearly seen that time is an important component of trade and in turn, affects the competitiveness of textile products As in the future, there would not be the competitions between companies but between their supply chains An average for the lead time of production and delivery of textile is 60-70 days, in comparison with only 50-60 days in China, Malaysia and Thailand One way to shorten lead time is to improve logistics from procurement, operation to delivery and sales to customers - Promoting Free Trade Agreements to lower tariff Regarding the effects of Free Trade Agreement (FTA) on intra-industry trade in the case of Textile Sector in Vietnam, it is found that bilateral and regional FTAs bring the opportunities for Vietnam to eliminate tariff and non-tariff barriers to trade 18 and investment among member countries It is proposed that Vietnam should prepare for the formation and enforcement FTAs to enjoy greater benefits Developing sub-supporting industries becomes important issues and urgent decisions to raise competitiveness of textile industry As many companies have proposed, the government should establish an industrial cluster to concentrate manufacturing factories near the sources of raw materials Besides, waste water from dyeing and washing process and other removals from cutting, sewing and button filling which may pollute the environment should be treated well through legal requirements and checkups According to economic experts, following FTAs, there would be more and more FDI and ODI pouring into developing countries such as Vietnam in the upcoming years and the government should take these advantages to call for investments into waste treatment processes and advanced technologies to improve efficiency while reducing the impact to the environment REFERENCES Hummels, D, Ishii, Jand Yi, K.M., 2001 The nature and growth of vertical specialization in world trade,
